IMPROVEMENT IN LAMP-SHARES.

TO ALL PEPSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, HENRY M. HARTSHORN, of Malden,in the county of Middlesex, and State of Massa chusetts, have invented u. new and useful or improved Folding Lamp-Shade; and I do hereby decl-aro the same to be fully described in the following specification, and represented in the accompanying drawings, of which-1 Figure 1 is a top view, and

Figure 2 a bottom view of n. shade as unfolded'or open 'and ready for use ons lamp-chimney.

Figure 3 isa. side view of it in a. folded state.

It is composed of a. series of trapezoids, a a a, of paper, arranged edge to edge, each being connected to that next to it by a strip of cloth, b, cemented to both so as to forma. hinge or ilexile connection, such as will enable one section to be turned down dat upon the other, and the whole to befolded into the form shown in fig. 3. Thereis a series of supporters, c c c, made of wire, projecting from the shorter bases of the several trapezoidal sections, there being one of such supporters to each of the sections. Each of the said supporters may have the form as shf-wn in figs. 1 and 2, or it may be formed and arranged with the section in manner as shown in Figure 4, in which it ispertially exhibited in dotted lines. It is also shown in figs. 1 and 2, it being held in place by a. layer of cloth, d, pasted onit and the inner surface of the trapezoidal section.

When the shade is applied to a tapering lamp-chimney, the upper parts of the supporters encompass and rest on the chimney, and thereby support the shade in place about the ame of the lamp.

I claim as my'inventon the folding shade made of trapezoids, connected ut their edges by strips of cloth, or the equivalent thereof, so that the several sections may be either folded or unfolded as specified.

I also claim the combination, as well as the arrangement, ofthe series of sectional supporters c, and afolding shade composed of a series of trapezoids, a, arranged and connected or hinged together et their edges substsntiallyjn manner as specified.

HENRY M. HARTS-HORN.
